DEFT: Advanced Structures and Applications.
Abstract
During the period covered by this report, major progress was achieved in several areas, including the CdS sensor, light valve, and applications. The major impetus to this work is the desirability of a real-time, programmable sensor for use in image and signal processing. The basic result from any of these devices is a detected electronic signal current. The 30 MHz CdS/LiNbO3 sensor can now be routinely fabricated as a monolithic structure, using a metallized polymer pedestal for sampling. This permits the device to be incorporated in a camera-like box with a highly convergent commercial lens for use under typical incoherent illumination conditions. Extensive effort has led to the successful operation of both 35 MHz and 100 MHz devices based on our experience with the 30 MHz structure. Beyond the extra care required during the photolithography in order to obtain the three-fold increase in resolution, we had to overcome an excessively large acoustic loss encountered at the higher frequencies.
